2023 ‘smashes’ records
RECORD-SHATTERING: 2023 “smashed” the record for the hottest year by a large margin, reported the Guardian. The newspaper said on Tuesday that, according to the EU’s Copernicus Climate Change Service, 2023 was 1.48C hotter than pre-industrial times. This is 0.17C higher than the last record set in 2016 – “marking a very large increase in climate terms”, according to the Guardian. And today the record was confirmed by the UN’s World Meteorological Organization, which has just published the findings of six leading climate datasets.
CHARTING CHANGE: In its coverage of the data, BBC News produced a number of charts and figures illustrating the path of global warming. Its analysis showed that almost every day since July has seen a new global air temperature high for the time of year. Meanwhile, the Independent published a feature examining whether 2024 could be even hotter than 2023.
STATE OF THE CLIMATE: Carbon Brief has just published the last of its quarterly state of the climate updates for 2023. It explains that 2023 was the warmest year “by a large margin”, at between 1.34C and 1.54C above pre-industrial levels across different datasets. Last year was also the warmest on record for ocean heat content, which increased notably between 2022 and 2023.
UK MP quits over fossil fuels
‘TRAGEDY’: The UK’s former energy minister Chris Skidmore quit as an MP in protest at the government’s plans to drill for more oil and gas in the North Sea, the Financial Times reported. In his resignation letter, Skidmore said it was “a tragedy that the UK has been allowed to lose its climate leadership” under prime minister Rishi Sunak, according to the newspaper.
BILL DELAYED: Skidmore quit over the government’s offshore petroleum licensing bill, which aims to “maximise” new oil and gas production, the FT said. The bill was due to be read in the House of Commons this week, but ended up being postponed, the Times reported. BBC News reported that Sir Alok Sharma, the Conservative MP and COP26 president, said he would vote against the bill, calling it “a total distraction” which reinforces the idea the UK is “not serious” about tackling climate change.
Renewables on the rise
RECORD RENEWABLES: A boom in Chinese solar power drove another record-breaking year of renewables growth in 2023, according to a new International Energy Agency (IEA) report covered by Carbon Brief. The world is now on track to build enough solar, wind and other renewables over the next five years to power the equivalent of the US and Canada combined, according to Carbon Brief’s analysis of the findings.
UK SOLAR: Along with the increase in global renewable capacity, there has been continued growth in low-carbon upgrades on UK homes, with solar and heat pumps driving record installations in 2023, according to separate Carbon Brief analysis.
Around the world
- US COAL DROP: US emissions fell by 1.9% in 2023, largely due to coal declining to its lowest level in 50 years, the New York Times reported. By contrast, US oil and gas production is set to hit a record in 2024 and 2025, said the Financial Times.
- ‘A LA CARTE’: Saudi Arabia’s energy minister has claimed that the headline COP28 agreement to transition away from fossil fuels is just one of several “choices” on an “a la carte menu”, reported Climate Home News.
- WAR EMISSIONS: Israel’s assault on Gaza since 7 October has produced more greenhouse gas emissions than 20 of the world’s most climate-vulnerable countries create in a year, according to new analysis covered by the Guardian.
- GERMANY PROTESTS: Farmers took to the streets of Berlin to protest against the German government’s decision to cut agricultural subsidies, Deutsche Welle reported.
- DEEP SEA MINING: Norway has become the first nation to approve commercial deep-sea mining, opening up a vast area of the Arctic to the extractive practice despite warnings from scientists, Mongabay reported.
- OFFSETS CONTROVERSY: The first-ever carbon-offset exchange under a new Paris Agreement mechanism, involving Switzerland buying credits for the rollout of electric buses in Thailand, is facing integrity questions, Climate Home News said.
40%
The proportion of North Sea oil and gas licences in UK waters owned by foreign companies and investors, according to EnergyMonitor.
Latest climate research
- A new research paper in Nature Climate Change presented a “conceptual framework” for considering the role of justice within climate research.
- The presence of urban green space is associated with “significantly lower rates of violent crime committed outside”, according to an International Journal of Biometeorology study conducted in Australia.
- A pair of studies in the Journal of Climate delved into an “exceptional heatwave” in east Antarctica in 2022, which brought “widespread 30-40C temperature anomalies across the ice sheet”.

Captured

A record 42 editorials opposing action to tackle climate change were published by UK newspapers in 2023, according to new Carbon Brief analysis. Written almost exclusively by right-leaning papers, these editorials called for delays to UK bans on the sale of fossil fuel-powered cars and boilers, as well as for more oil-and-gas production in the North Sea, according to the findings. In response to such demands, prime minister Rishi Sunak performed a “U-turn” in September on some of his government’s major net-zero policies.
Spotlight
Investigating Antarctica’s colossal icebergs
This week, Carbon Brief speaks to Dr Oliver Marsh, a glaciologist who is principal investigator of a British Antarctic Survey (BAS) mission currently studying iceberg calving events at Antarctica’s Brunt ice shelf (pictured).

Carbon Brief: Can you please explain what fieldwork you are currently working on?
Dr Oliver Marsh: We are drilling ice cores to collect ice samples from the Brunt ice shelf. These will be brought back to Cambridge [where BAS is located] and University College London (UCL) in order to test their physical and chemical properties. We are also setting up seismic and GPS equipment to monitor fracture growth and strain rates on the ice shelf. We will then link the properties of the ice to the behaviour of the fractures.
CB: What do you hope to find out by conducting this fieldwork?
OM: We are interested in the mechanism and timing of crack growth leading to iceberg calving [where chunks of ice break off from the front of a glacier]. In particular, we want to understand how changes in ice properties change calving rates. The ice shelf we are working on has a well-documented history of crack growth, with two large calving events in the last three years, and the new information we gain from precise laboratory measurements will help us to understand how – and under what conditions – fractures occur in the lead-up to these calving events.
CB: What are the biggest hazards with conducting fieldwork on the Brunt ice shelf?
OM: The Brunt ice shelf is a good location to monitor fracture growth due to its dynamic behaviour. This means there are rifts and other cracks in the ice that can be hazardous for travel. These cracks are heavily monitored with a suite of geophysical instruments, including ground-penetrating radar, GPS and satellite data, and precautions are taken when moving around. Fieldwork in Antarctica also has significant hazards associated with the weather, for example, strong winds and wind chill.
CB: How is climate change affecting iceberg calving events in Antarctica?
OM: Calving occurs as a normal process of ice loss from the continent. But, as it occurs in discrete events and very infrequently for some ice shelves, it is difficult to determine whether rates are changing from a short satellite record. Other fracturing processes, such as hydrofracture and ice shelf collapse, are linked to both ocean and atmospheric warming, so it is possible that calving rates may increase in the future.
CB: What would be the implications of accelerated iceberg calving for the climate and ecosystems?
OM: Increased calving is likely to weaken ice shelves that fringe the continent and support the glaciers inland. This can help to speed up glacier flow and ice loss to the ocean, contributing to sea level rise. An increase in the volume of icebergs may also cause issues for ecosystems, particularly in areas where icebergs ground on the ocean floor, blocking foraging routes for penguins and seals, for instance.

Climate Change
As fires burn and temperatures soar, it’s time to imagine a world beyond GDP
Steven Stone is acting director of the United Nations Environment Programme’s Office of Science
In 1934, American economist Simon Kuznets presented a paper to Congress advocating for a new way of measuring economic performance.
The United States was reeling from the Great Depression, and Kuznets – a future Novel prize winner – wanted to gauge just how badly the country’s economy had been dented.
His metric, which would come to be known as gross domestic product (GDP), was a breakthrough. But as pioneering as it was, Kuznets saw its limitations.
“The welfare of a nation can scarcely be inferred from a measure of national income,” he wrote in the 1934 paper.
Some nine decades on, we have largely forgotten that message. GDP has become a barometer of economic progress, a kind of one-number-that-rules-them-all upon which national policies turn and governments rise and fall.
With the climate crisis deepening by the day – as evidenced by the heatwaves and wildfires now searing Europe – our attachment to GDP is looking like a problem.
In a single-minded pursuit of GDP growth, humanity is inadvertently feeding several environmental crises that, over the long run, threaten to make most of us poorer, sicker and more miserable. Climate change alone could slice 20 per cent off global GDP by 2100 – a staggering number.
Clear-cutting boosts GDP not wealth
We need to broaden our vision and definition of economic success before it’s too late.
I grew up in the 1970s and 80s surrounded by the mixed hardwood forests of the northeastern United States. For me, the trees were a refuge, a place to run, discover and savor the history and mystery of the land and its people.
Those experiences with my friends were more important than the amount of money in my pocket. And they led to a realization early on in my career as an economist: that wealth is about more than just income.
This is one of GDP’s most significant oversights.
With every forest we clear cut and every ounce of fossil fuel we burn, GDP rises. But through those actions, we are whittling away at the natural world, which supplies us with food, water, medicine, clean air and countless other essentials.
By focusing only on GDP, we’re ignoring what’s happening to the natural assets on which our prosperity ultimately depends. It’s like we’re driving a car and only looking at the speedometer, not the energy remaining in the battery.
That is the difference between measuring income versus measuring wealth.
The answer to this dilemma lies in looking beyond GDP. We must start considering a broader range of indicators when making policy decisions.
From an environmental perspective, that means measuring and valuing natural assets like forests, water, soil, biodiversity and clean air. By assigning a value to nature, decision-makers can better understand the economic consequences of, say, strip-mining a mountain top or letting plastic waste overwhelm a river.
There is still some debate over how exactly to do this kind of natural capital accounting. But that’s not a reason to dismiss it, as many have done. It took years of refinement to end up with the GDP formula we have today.
Costa Rica’s example
The idea of looking beyond GDP isn’t only a theoretical debate. Countries and communities around the world have started to make economic decisions based on their natural assets. A prime example is Costa Rica, a biodiversity hotspot where a years-long effort to conserve land and seascapes has led to a boom in tourism. That in part helped elevate the country into the club of high-income nations.
This kind of environmentally focused economic decision making can pay huge dividends. By stabilizing the climate, ending pollution and halting the loss of the natural world, humanity could save millions of lives a year and create US$20 trillion in economic benefits annually by 2070, found the Global Environment Outlook 7, a 2025 report from the United Nations Environment Programme (UNEP). The report was funded by the European Union among others.
I began my career as an economist before moving to UNEP, which focuses on solving the world’s thorniest environmental problems. During that time, I’ve come to appreciate that “wealth” means more than simply “income.” True prosperity means being able to provide for ourselves now and into the future. Anything short of that is an empty kind of affluence – and ultimately doomed to be short-lived.
As deadly heat blankets our cities, species slip into extinction and the planet struggles with rising toxicity and pollution, I am convinced that we can do better at measuring what matters. And that means updating and expanding how we measure economic progress.

Climate Change
When taps run dry in the Caribbean, it’s not enough to blame El Niño
Amira Odeh Quiñones is a hydrologist and Caribbean organiser for the 350.org climate campaign group
El Niño, likely to be one of the strongest in modern history, has arrived on Caribbean shores.
Drought is slowly creeping up on our islands. But unlike the fiery wildfires ravaging parts of Europe, there’s no smoke signalling the damage being done, no sirens to warn of the danger. Only announcements from public health officials to stay indoors and remain hydrated — as if outdoor workers and farming communities have the luxury to heed such advice.
During El Niño, strong atmospheric winds alter rain patterns and trap heat across the Caribbean. But while we have experienced El Niño many times before, it has become very visible in recent years how climate change is making this natural phenomenon worse.
Across the Greater Antilles, temperatures are soaring past 38°C (100°F), with real-feel indexes reaching a gruelling 43°C in parts of Puerto Rico where I live. Cuba has it worse. Widespread power outages mean that methods for cooling down are unavailable for most of the day, leaving millions of vulnerable people at risk of heat stroke when temperatures hit 38°C.
Santa Marta coalition tested as co-chair Colombia turns back to fossil fuels
During the last strong drought a decade ago, I had water only two days a week in my home. Today, there are many families whose taps are about to run completely dry. Water authorities have already begun strict rationing in some municipalities, with more on the list scheduled for rationing if conditions don’t change.
Water rationing is far more than an inconvenience; it is an immediate health risk. This means thousands of people need to constantly haul heavy buckets up flights of stairs just so they could bathe, cook, stay hydrated – the basics of survival.
Heat causes health problems
Puerto Rico is home to roughly 300,000 elderly residents. Many live alone, isolated and without support. They risk severe physical injury when carrying heavy water containers, and are wont to suffer from silent heat exhaustion in unventilated rooms.
Furthermore, when water shortages force residents to store water in open household containers, it inadvertently creates breeding grounds for Aedes aegypti mosquitoes. Paired with scorching temperatures that tend to shorten the mosquito breeding cycle, the region is facing explosive outbreaks of dengue fever that endanger our most vulnerable: children and the elderly.
The economic fallout is equally devastating. Dry fields mean millions of dollars in lost crops, forcing small agricultural businesses to collapse, needing urgent government relief to survive. Extreme fuel shortages have already paralyzed Cuba’s agricultural sector, cutting food output by 60% – the El Niño dry spell threatens to decimate it.
At sea, warmer ocean waters fuel massive influxes of sargassum seaweed. Rotting sargassum chokes our beaches, destroying the local tourism industry that so many working families rely on. Tangled seaweed also damages nets and boat engines, slashing fish catches and driving up equipment costs for local fishers.
In the south of Puerto Rico, the coastal town of La Parguera is currently witnessing a historic amount of sargassum on its shores. This has halted most of the boating activity in the area, which is the seaside town’s main tourist draw and economic driver.
All over the Caribbean, from town halls to local group gatherings, the story I hear is always the same: constant headaches, lost work hours, failing health, and a sense that quality of life is silently being stolen. The compounding effects of heatwaves, drought, and marine destruction are exhausting our people, our islands.
Climate change to blame
Climate change makes each El Niño year hotter and more damaging. Higher baseline global temperatures increase the energy and moisture available for extreme weather. Latest projections show that El Niño may push the monthly global average temperature past 2°C of warming for the first time in early 2027. In the Caribbean islands, that will not just be breaking records – it’ll be breaking lives.
Recently, I had the opportunity to share a panel with climate scientists behind what is known as the field of “attribution science” – or the science that compares today’s climate conditions to what the Earth’s climate would be like without human activity, particularly burning fossil fuels. They’re unequivocal: it’s no longer a question of whether extreme weather is caused by climate change, it’s just a question of how much.
Attribution science recently got a boost from the U.S.’ top scientific advisory body. The National Academies of Sciences, Engineering and Medicine recognized that researchers’ methods have advanced considerably in recent years, resulting in better assessments on how much extreme weather can be attributed to human-caused climate change. It noted that attribution findings could be relevant in some types of legal cases, including those seeking damages from oil companies for climate impacts.
This crisis, which is already taking a heavy toll on our communities’ survival, needs real, urgent, and structural action that goes beyond aid. With similar droughts now gripping parts of Asia and Africa, we’re falling into the familiar narrative of treating the looming humanitarian crisis as if no one was to blame, as if it is being caused solely by a natural phenomenon we can’t control.
It’s not. The world was already on fire before its regular visitor, El Niño, came. While we need humanitarian action, we need climate action too, in order to permanently put out the flames.

Q&A: What is in China’s new five-year plan for climate change?
China has released a five-year plan dedicated to addressing climate change.
The 15th five-year plan for a national response to climate change is the latest in a series to outline in-depth climate and energy targets for the 2026-2030 period.
These include five-year plans for “building a Beautiful China”, developing a “new-type energy system” and developing renewable energy.
There are also separate “action plans” for the 2026-2030 period, such as for peaking carbon emissions.
China has pledged to peak its emissions before 2030 and reach carbon neutrality before 2060.
The new plan does not include any major new targets, instead consolidating and reaffirming existing policies.
Nevertheless, it includes significant signals on key policy areas, such as non-carbon dioxide (CO2) greenhouse gases, global climate governance and carbon markets.
Below, Carbon Brief examines some of the notable elements in the latest five-year plan and what it reveals about China’s policy direction through to 2030.
What does the climate plan cover?
The Ministry of Ecology and Environment (MEE) released the plan in late July, in unison with 18 other government departments. These include the National Development and Reform Commission (NDRC), China’s top economic planning agency, and the National Energy Administration.
The document covers a range of topics, including CO2 emissions, other greenhouse gases (non-CO2 GHGs), carbon markets, carbon footprints, climate adaptation and international cooperation on climate change.
For the first time at the five-year plan level, the plan creates a comprehensive target system covering all areas of climate policy, say officials in a MEE Q&A.
They describe it as “the main policy instrument” for advancing China’s climate action during 2026-2030.
China rarely issues high-level multi-year policies dedicated to “responding to climate change”. In 2014, the NDRC published a plan on the topic running through to 2020, but this was not linked to a five-year plan period.
Qin Yan, principal analyst at ClearBlue Markets, tells Carbon Brief that the plan shows that China’s climate governance has reached “an unprecedented strategic level”.
She adds that the plan creates an “all-encompassing target system” to support China’s Paris Agreement climate pledges for 2030 and 2035.
In its 2030 pledge, China aimed to peak emissions “before 2030” and reduce carbon intensity – its emissions per unit of GDP – by more than 65% from 2005 levels.
Last year, president Xi Jinping personally announced China’s 2035 pledge to cut China’s greenhouse gas emissions to 7-10% below peak levels by 2035, while “striving to do better”.
The five-year plan marks a new phase in China’s climate policy, according to researchers at CIB Research, an economic research body affiliated with the Industrial Bank, whose largest shareholder is the Fujian provincial government.
Their analysis adds that the plan represents a broad effort to strengthen China’s climate-governance system, implementation mechanisms and underlying capacity.
Nevertheless, several headline targets and policies in the document simply reiterate already established plans.
These include:
- Cutting carbon intensity by 17% across the five years
- Reducing carbon intensity per product in industries under China’s carbon market by 3%
- Substituting fossil fuels with renewables
- Strengthening climate adaptation
- Supporting the “free flow” of cleantech
What does the plan say about non-CO2 GHGs?
The plan also goes into detail on China’s approach to non-CO2 GHGs. This includes reaffirming a target of an emissions “reduction capacity” from these gases totalling 30m tonnes of CO2 equivalent (MtCO2e) by 2030, although the baseline is unclear.
The target previously appeared in the overarching five-year plan, as well as the plan for building a “Beautiful China”.
The goal refers to emissions reductions, which can be realised through implementing current non-CO2 emissions reduction policies and projects, says Chen Meian, programme director and senior analyst at the Institute for Global Decarbonization Progress (iGDP).
She adds that it is “relatively achievable”, with sources including increasing the number of coal-mine methane utilisation projects.
She points to an MEE explanatory note for a draft methodology under the China Certified Emission Reduction (CCER) scheme, China’s voluntary carbon-credit market. Chen says the note suggests that projects using ventilation air methane and coal-mine methane with concentrations below 8% alone could deliver around 20MtCO2e of reduction by 2030.
The note states that, currently, such projects are estimated to be able to “generate annual emission reductions of approximately 4.5MtCO2e”.
In addition, Chen says, measures targeting industrial nitrous oxide (N2O) and hydrofluorocarbons (HFCs) could help make up the remainder needed to meet the target.
According to iGDP analysis of biennial reports submitted by China to the UNFCCC, China emitted around 14,000MtCO2e of GHGs in 2021, excluding land use, land-use change and forestry (LULUCF).
Non-CO2 GHGs accounted for around 2,700MtCO2e, or 19%, of the total, the majority of which was methane, as shown in the figure below.

China’s plans to curb these super-pollutants in the five-year period include coal-mine methane utilisation projects, end-of-pipe destruction technologies for HFCs and guidance on the use of catalysts to reduce N2O emissions.
The plan also calls for the recovery and replacement of sulphur hexafluoride (SF6) in power equipment.
For Chen, the plan’s focus on SF6 control is particularly noteworthy. She says the gas is “finally receiving policy attention” and that proactive action is “timely and will help avoid future emissions growth” as China’s power system expands.
What does the plan say about global climate governance?
One of the plan’s clearest objectives for international cooperation is for China to play a more active role in global climate governance.
By 2030, it says China should markedly increase its “influence, guiding power, shaping power and moral appeal” in this area.
It says China’s climate action could also feed into the Global Governance Initiative, a policy initiative aimed at reforming the global governance system.
China will also aim to “build a new narrative on climate governance”, it adds.
Prof Thomas Hale, a professor in public policy at the University of Oxford’s Blavatnik School of Government, writes on LinkedIn that the plan “marks a major rhetorical shift” towards China being increasingly willing to “lead and shape” global climate action.
Another clear focal point for international cooperation is in carbon markets.
The plan calls for China to expand the global influence of its carbon market, such as through international rule-setting, cooperation on standards and by hosting the China Carbon Market Conference.
Qin says China’s more active role in global carbon pricing is already evident in the launch of the open coalition on compliance carbon markets with the EU and Brazil. This coalition is expected to adopt a work plan at the China Carbon Market Conference in September.
Qin also notes that China “could become the world’s largest [carbon] offset buyer” as its energy transition progresses.
The country would, therefore, “benefit from helping shape global rules under the Article 6 framework [for carbon trading under the Paris Agreement]”, she adds.
